How many audiophiles do you need to change a lightbulb?

Real audiophiles don't need the extra radiation from the lightbulb interfering with their setup or their eyesight taking away some concentration from their hearing.

I have super efficient lamps. Therefore I only need 1watt bulbs. 

What's your budget? Is the power source directly connected to the wall outlet or a filtered power source?  Are we talking incandescent, halogen, CFL or LED? All these factors determine the number of Audiophiles involved. 

It actually only takes one knowledgeable audiophile with some experience and technical skills. It's not too difficult. But after the bulb is installed, burnt in, and calibrated you'll need at least two people to do room treatments and place infrared traps in the corners.
